I have had 8 trades since I started learning to trade 2 months ago. So far all losses. Three of those losses were disciplined trading (cut losses quickly if stock doesn't do as anticipated/targeted). The remaining 5 were classic embarrassing revenge trading.

In total, I am down 223 USD (commissions included) from my starting 1800 USD account. So in terms of portions (commissions included): 136 USD lost due to stupid revenge trading; 87 USD lost due to disciplined loss cutting. Vengeance really doesn't pay...I paid for it.
